PRINTERS CHASE.

Application led 'March 24, 1922. Serial No. M6339.` v

To aZZ whom t may concern,

Be it known that I, ALBERT C. EVANS, a

citizen of the United States, and a resident frame.

of. Butte, in the county of Silverboiv. and State of .ll/lontana, haveinvented certain new and useful Improvements in Printers Chases, f whichthe following is a specification. l l

VMy. invention'relates to printers chases and the purpose of myinvention is the provision of a chase by means, of which a type formlcan be quickly andv accurately centered Within the chase Withoutthenecessity of measuring, and in such manner that vthe number f picas offurniture necessary to confine the form in centered position will beautomatically indicated.

I will describe one form of chase embodying my invention and will thenpointent the novel features thereof in claims.

In the accompanying drawings:

VFigure 1 is a view showing in top plan'one form 'of chase embodying myinvention.

Figure 2 is a transverse sectional view taken on the line 2-v-2 ofFigure 1.

Referrin specifically to the drawin in which simi ar referencecharacters re er to similar parts, my invention in its presentembodiment comprises a metallic frame F of rectangular outline, which isthe usual construction of chase.- Along the side/and end inner edges ofthe frame, graduations indicated at G are provided which are .numberedand so arranged as -to forni a.

plurality of linear and printers scales as indicated at S, with twoscales along each transverse and longitudinal edge of the Thegraduations of each scale are arranged to define the distance in inchesand picas, .with the numerals of any pair of scales progressivelyincreasing in denomination from the corner of the frame to a pointmedial of the corners. In the present instance the picas are indicatedin multiples of three, although it is to be understood that every picamay be designated or any multiple thereof. rhe common terminal of thescales along-each sidca'nd end of the frame is indicated by the heavyline designated at L, and each line L defines the medial point along theends or sides 0f the frame so that tivo lines drawn from the lines L soas to intersect each other at right :ingles will define the exact centerof the frame at the point where thc lines intersect.

In practice, the type vforni is adjusted within the chase anni the inch01'? picas graduations appearing ati the opposite sides. are the' sameand those at the opposite end-s are the same. For example, take a type@0 form f l picas long and 24 picas wide. The form is adjusted until thenumberL of picas at eachside of the form is'l22, and the number of picasappearing at the end of the s@ mf form isl8. When the type forms arepositioned it is. accurately centeredwith respect tothe chase, thuseliminating the meas# uring operation which would be necessary with allchases heretofore proposed.

The n umber of picas appearing at the op-y posite sides or ends of thetype form indicate the number of pieces' of furniture to be placed inthe chase for confining the type `form in centered position', so that'by ap? Plyng the necessary number of pieces :m/75 Subsequently applyingthe quoins, the type form. can be secured in accurately centeredposition Within the chase.

, Although I have herein shown and de-` l scribed only one form o fprinters chase enibodying my invention, itis to be understood thatvarious changes and modifications may be made herein Without departingfrom the spirit of the' invention or the spirit and scope` oftheappended claims.

What I claim is:

LA printers chase comprising rigidly4` connected together pairs ofspaced parallel longitudinal members and spacedl parallel transversemembers at the ends of the longitudinal members and having a printersscale extending on one longitudinal member adjacent to an inner ed ethereof and having a Vprinters scale exten ing on the corresponding faceof a transverse member of the chase adjacent to the inner edge of thetransverse member, each of, said printers scales comp rising picamarkings increasing progressively in denomination from the ends of thechase member on which provided to the mi) transverse median linethereof, whereby the positions of type forms of various sizes when incentered relation to the chase and the number of picas of furniturerequired to secure the type forms in centered relation to the chase maybe accurately determined.

2. A printers clse' comprising rigidly connected together pairsof spacedparallel .longitudinal members and spaced parallel transverse members atthe ends of the lon 110 gitudinal members and having a printers scaleextending on one longitudinal niember adjacent to an inner edge thereofand having a printers seule extending on the corresponding face of a,transverse member of the chase adjacent t0 the inner edge of thetransverse member',A en eh of said printers scales comprising picavmarkings increasing progressivey in denomination from the ends of thechase member on whichf provided to the transverse median line thereof,said transverse median line being clearly indicated by a markingcoincident therewith, wherebyl the positions of'type forms of varioussizes when in centered relation to the 'ehase and the number of picasleffirniture required to secure the type forms' ientered relation to thechase may be aeeurately determined.

8.,A printers chase comprising rigidly connected together pairs ofspaced parallel longitudinal mambers 'and spaced parallel temetetransverse members having a printers scale v extending along the inneredge thereof from the plane of the inner edge of one longitudinal memberto the plane ofthe inner edge of the other longitudinal members, each ofsaid printers scales comprising pica merKings' increasing progressivelyin denomination from the ends of the scale to the transverse median linethereof, whereby the scales will indicate the number of picas offurniture required to lock type forms of various sizes in centeredrelation to the chase.
